What is Photosynthesis?Photosynthesis is the biological process by which plants, algae, and certain bacteria convert light energy into chemical energy to fuel their growth.It occurs in chloroplasts, where pigments like chlorophyll absorb sunlight. During photosynthesis, carbon dioxidefrom the air and water from the soil are combined toproduce glucose and oxygen.This energy-conversion process is fundamental forsustaining life on Earth, as it generates the oxygen webreathe and provides the foundation of the food chain, asplants serve as primary producers
